Saturn at Sunrise on 2021-05-31 with vintage Celestron C8

Planetary Season has begun for me. And boy, I am rusty. I spent so much time with all the basics of aligning, adjusting and connecting the software that I did not have enough time for a decent collimation with MetaGuide anymore.

I managed to capture two 4min videos of Saturn. Seeing was soso and the rising sun prevented a third video. What I take from this is a) to always check and align your red-dot-finder as the first thing and b) that a motor focus rocks!

Above is a 20% stack of 11k frames across 240s. With Barlow and ADC the scope was at 4750mm focal length (making it f/24) - slightly oversampled. Data is rescaled from 0.16"/px to 0.19"/px for better sampling (equivalent to f/20 and 4000mm focal length). Processed in AS!3, RegiStax, AstroSurface and AffinityPhoto.

Color balance is not so good. Sunrise really messed this up - my usual routines did not work so well this time.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
